Happy 37th birthday, Alchemist! The West Coast producer is celebrating his birthday by gifting you with some unreleased music; what a guy! For his 37th Al has uploaded a previously unreleased track he had stashed away in the vault. That track is “Biology” by Queens legends Mobb Deep. Listen after the jump.

This is one of the best videos I ever found. Videos like this are the reason I love the internet. I found this a while ago. This is the Nas Electronic Press Kit for his debut album “Illmatic”, my (and a lot of other peoples) favorite hip hop album of all time. This video is wild. It features the production lineup from the album (Dj Premier, Large Professor, Q Tip & Pete Rock) discussing Nas and the making of the album. It also features Nas’ original home Queensbridge Projects and a cast of people that live there. This was the begining of a new era in rap that came as quick as it went. Enjoy.
